基于综合评价模型的区域耕地质量评价与空间集聚研究陈逸飞施晓辉朱春成王晓瑞摘要从耕地质量的综合性、生产性、生态性出发，界定了耕地质量包括自然质量、生产质量、绿色质量3个层次的内涵，建立了耕地质量评价的综合模型。通过土壤样品采集与外业调查获取相关数据，应用综合评价模型评价区域耕地质量，并研究耕地质量的数量及空间分布规律。结果显示，研究区自然质量、生产质量、绿色质量、综合质量分别平均为2.6级、2.4级、2.3级、3.3级，较好地反映了区域自然条件水平、生产能力水平、作物质量水平;评价结果空间集聚特征明显，绿色质量高等级地主要集聚于西部地区，自然质量、生产质量、综合质量高等级耕地主要集聚于东南部地区，各层次的耕地质量可为区域耕地保护、粮食安全保障及农业可持续发展提供科学依据。关键词耕地质量;空间集聚;综合评价模型;江苏省东海县F301.2A0517-6611（2020）15-0078-07doi：10.3969/j.issn.0517-6611.2020.15.023开放科学（资源服务）标识码（OSID）：EvaluationofFarmlandQualityandSpatialVariationBasedonComprehensiveEvaluationModel—TakingDonghaiCounty，激angsuProvinceasanExampleCHENYifei1，SHIXiaohui2，ZHUChuncheng2etal（1.YangzhouUniversity，Yanzhou，激angsu225000;2.BoyuanPlanningandDesignGroupCo.，Ltd.，Nan激ng，激angsu210004）AbstractBasedonthecomprehensiveness，productivityandecologyoffarmlandquality，theconnotationoffarmlandqualityincludingnaturalquality，productionqualityandgreenqualitywasdefined，andacomprehensiveevaluationmodeloffarmlandqualityevaluationwasestablished.Relevantdatawereobtainedthroughsoilsamplecollectionandfieldsurveys，acomprehensiveevaluationmodelwasusedtoevaluateregionalfarmlandquality，andthequantityandspatialdistributionoffarmlandqualitywerestudied.Theresultsshowedthatthenaturalquality，productionquality，greenqualityandcomprehensivequalityofthestudyareaaveraged2.6，2.4，2.3，and3.3，respectively，whichreflectedtheaveragegradesofregionalnaturalconditions，productivityandcropquality.Thespatialaggregationcharacteristicsoftheevaluationresultswereobvious.Thehighqualitygreenqualitylandwasmainlyconcentratedinthewesternregion，andthehighqualityfarmlandofnaturalquality，productionqualityandcomprehensivequalitywasmainlyconcentratedinthesoutheastregion.Differentlevelsoffarmlandqualitycanprovideascientificbasisofregionalfarmlandprotection，foodsafetyandsustainableagriculturaldevelopment.KeywordsFarmlandquality;Spatialcluster;Comprehensiveevaluationmodel;DonghaiCountyof激angsuProvince作者簡介陈逸飞（1999—），男，江苏盐城人，从事水利工程研究。-全文完-
